Description générale

The Progard® 2 Pretreatment Pack is designed to pretreat water by removing large particles, organic compounds and free chlorine from tap water. This protects the reverse osmosis (RO) membrane against mineral scaling, organic fouling and chlorine oxidation. Progard® 2 Pretreatment Pack ensures that your system lifetime and performance are optimized. Designed for use with AFS®, Direct-Q® Elix® and RiOs 5/8/16 water purification systems. Replacement of consumables when requested by the system is key to maintain the system′s performance within specifications.


Removal of organics, free chlorine, particles and colloids from tap water for optimal protection of the RO membrane.

Caractéristiques et avantages

  • The Progard® 2 pretreatment pack is constructed from polypropylene and EPDM.
  • Suitable for tap water feed with silt density index (SDI) < 12, Cl2 < 3 ppm and TOC < 2000 ppb.
  • Natural activated carbon media exhibits a high surface area and adsorption kinetic, tolerating feed water containing up to 3 ppm of chlorine and 2000 ppb of TOC.
  • Depth filter media exhibits a high capacity and optimized retention, tolerating feed water with SDI up to 12.
  • Incorporates polyphosphate, specifically selected to avoid scaling without releasing ions.
